In recent years, the Brazilian government has authorized several agricultural pesticides, increasing the possibility of pollution of different ecosystems and the food consumed by a large part of the population. The analytical determination of pesticides can be carried out using different techniques associated with various methods. Their development and validation have been based on obtaining better reliability, meeting the requirements of environmental legislation, and adapting to the principles of Green Chemistry. Thus, a chromatographic method was developed for the separation and determination of eight agricultural pesticides (aldicarb, ametrine, atrazine, bendiocarb, carbaryl, hexazinone, methiocarb, and methomyl) in compliance with Green Chemistry criteria, using ethanol as the mobile phase, which it is an ecologically less aggressive solvent. The developed method showed efficient separation and excellent results for green analysis metrics with high scores on the Eco-scale and good presentation in the National Environmental Methods Index (NEMI), Green Analytical Procedure Index (GAPI), and Analytical Greenness Calculator Metric (AGREE) pictograms. The validation parameters indicated the linearity of the method with good precision, selectivity, and sensitivity with detection and quantification limits in the ranges of 0.50 to 0.94 mg L–1 and 0.74 to 1.81 mg L–1, respectively. years population methods reliability legislation Thus aldicarb, aldicarb (aldicarb ametrine atrazine bendiocarb carbaryl hexazinone methiocarb methomyl criteria phase solvent Ecoscale Eco scale NEMI, NEMI , (NEMI) GAPI, GAPI (GAPI) AGREE (AGREE pictograms precision selectivity 050 0 50 0.5 094 94 0.9 L1 L 1 L– 074 74 0.7 181 81 1.8 respectively (NEMI (GAPI 05 5 0. 09 9 07 7 18 8 1.

Resumo A fragmentação florestal é um dos fatores que interferem na sustentabilidade dos recursos naturais, biodiversidade e qualidade de vida. Diante disso, são essenciais estudos que avaliem quanti e qualitativamente as propriedades ambientais de determinado ecossistema e/ou paisagem. Para tanto, a análise da ecologia da paisagem atua de forma eficaz. Diante disso o presente estudo buscou avaliar, a partir de métricas de paisagem, a qualidade dos remanescentes florestais presentes na parte da sub-bacia hidrográfica do rio Atibaia que cobre o município de Campinas/SP. Para tanto, utilizaram-se as métricas: Tamanho; Índice de Área Central; Índice de Circularidade; Distância do Vizinho mais Próximo; Proximidade à Curso d’Água; Produção de Água; Grau de Uso e Ocupação do Solo no Entorno e Grau de Erodibilidade do Solo. Estas foram analisadas individualmente e através do Índice de Qualidade Ambiental (IQrem). Verificou-se o alto grau de fragmentação florestal, dado o elevado número de remanescentes, especialmente pequenos e com baixa representativa de área central, porém localizados próximos uns aos outros. Além disso, por tratar-se de sub-bacia produtora de água para abastecimento, ressalta-se a necessidade de estratégias específicas de conservação desses remanescentes a fim de garantir a produção de água em termos quantitativos e qualitativos.

Abstract Forest fragmentation is one of the factors which interfere in the sustainability of natural resources, biodiversity and life quality. In view of this, studies that assess the quantitative and qualitative environmental properties of a given ecosystem and/or landscape are essential. Therefore, the analysis of landscape ecology acts effectively. Thus, the present study aimed to evaluate, based on landscape metrics, the quality of the forest remnants presents in the Atibaia river sub-basin covering the municipality of Campinas/SP. For that, the following metrics were used: Size; Central Area Index; Circularity Index; Distance from the Nearest Neighbor; Proximity to the Watercourse; Water Production; Degree of Land Use and Occupation in the Surroundings and Degree of Soil Erodibility. These were analyzed individually and through the Environmental Quality Index (IQrem). There was a high degree of forest fragmentation, given by the high number of remnants, especially small and with a low representative central area, however, located close to each other. In addition, as this watershed is a water-producing for supply, the need for specific conservation strategies for these remnants is emphasized, in order to guarantee water production in quantitative and qualitative terms.
